10 / 16 page  2000 Sep 05 10 Philips Semiconductors Product specification Rotational speed sensor KMI15/4 EMC Figure 18 shows a recommended application circuit for automotive applications (wheel sensing ft < 5 kHz). It provides a protection interface to meet Electromagnetic Compatibility (EMC) standards and safeguard against voltage spikes Table 1 lists the tests which are applicable to this circuit and the achieved class of functional status. Protection against ‘load dump’ (test pulse 5 according to “DIN 40839”) means a very high demand on the protection circuit and requires a suitable suppressor diode with sufficient energy absorption capability. The board net often contains a central load dump protection that makes such a device in the protection circuit of the sensor module unnecessary. Tests for electrostatic discharge (ESD) were conducted in line with “IEC 801-2” to demonstrate the KMI15/4’s handling capabilities. The “IEC 801-2” test conditions were: C = 150 pF, R = 150 Ω, V = 2 kV. Electromagnetic disturbances with fields up to 150 V/m and f = 1 GHz (ref. “DIN 40839”) have no influence on performance.
